I would think the first question would be whether or not there is a Progress installation on the machine somewhere. If that backup file was indeed created in May, then it seems likely. Also, who created that ... something else you could find in the log. Are they still around? Probably a lot easier if they know something and help. If so, then start a server and use the sql tools to access the database, either the vendor supplied ones or just sqlexp. Then query or dump depending on the actual need.
